A coil supporting bar 36 is firmlysecured to the tops of the bosses 29, bridging the space between them,and coils 3'! acting tocontrol movements of coin directing devices aresecured to said bar.

It will be noted that in all of these operations the bosses haveincluded three sides only, that is, they are closed on all sides withinthe dishshaped structure. This comprises an important feature of myinvention as a very stable and rigid support for the bar 36 and hencethe coils 37 is provided sufiicient to rigidly maintain the coils inposition and effectually resist movement'of the coils on the support byreason of jars, jolts or other abnormal causes.

I claim:

1. A sheet metal supporting plate for telephone mechanism, said platecomprising a bottom and sides located at an angle to said bottom, saidplate including a supporting boss of substantially rectangular shape incross-section rising from the plate at the angle between said bottom andsides and with relatively angularly disposed supporting sides extendingfrom the top of the boss to the plate on more than two sides thereof.

2. A sheet metal supporting plate for telephone mechanism, said platecomprising a bottom and sides located at an angle to said bottom, saidplate including bosses of substantially rectangular shape incross-section arranged at opposite sides of the plate at the anglebetween said bottom and sides and rising therefrom, and with relativelyangularly disposed supporting sides extending from the top of each bossto the plate on more than two sides thereof.

3. A sheet metal supporting plate for telephone mechanism, said platecomprising a bottom and sides located at an angle to said bottom, saidplate including a boss of substantially rectangular shape incross-section rising from the plate at the angle between said bottom andsides and with relatively angularly disposed supporting sides extendingfrom the top of the boss to the plate, said sides being continuous andunbroken from one boundary around the top to the opposite boundary ofsaid sides.

4. A sheet metal supporting plate for telephone mechanism, said plateincluding a dish-shaped structure with oppositely arranged side walls,and bosses of substantially angular shape in crosssection located at theangle between the side walls and plate at opposite edges of the latter,said bosses each including a top with relatively angularly disposedsupporting sides extending from the top to said plate on all sideswithin said side walls which form sides of said bosses.

5. A sheet metal supporting plate for telephone mechanism, said plateincluding side walls arranged at an angle to the plate and bosses ofsubstantially angular shape in cross-section located against said plateand side walls at opposite edges of the plate, each boss including a topand relatively angularly disposed supporting sides extending from thetop to said plate on all sides within said side walls and united at saidtop with said side wall, and a supporting bar bridging the intervalbetween said bosses.
